Application filed March 26, 1926. Serial No. 97,712;

This invention relates to ventilators, and

more particularly to what I term ugal ventilator for use on railw cars.

One of the main objects of the a centrifay dining invention is to provide a ventilator of simple and inexpensive construction which may be readily mounted in the window of a dinin during travel of the g car and,

car, will force air into the car from outside thereof. A further object is to provide a ventilator which will operate equally ling in either direction.

well when the car is travel- Further objects will appear from the detailed description.

the venti- Fig. 6 is a section taken substantially on line 6-6 of Fig. 4:.

taken substantially on Fig. 8 is a fragmentary section through the ventilator fan hub.

The ventilator includes a box like casing 1 which is divided by partitions 2 into end compartments 3 and 4. A shaft 5 is rotatably mounte each end compartment 3'- wheels 6 are secured on this a center compartment d through and two wind shaft, each wheel including disks 7 between which are mounted vanes 8 disposed radially of the wheel, the

outer end of each wardly vane being turned insubstantially at right angles to provide an end flange 9. A hub 10 is mounted on shaft 5 between wheels 6 11 which passes about hub 12 of a fan 13, hub 12 and is provided with a central groove which receives a cord ventilator being provided with spaced grooves l l'for the reception of the cords 11. Fan 13 is rotatably mounted on a shaft'15 secured through front and back supporting strips 16 and 17 respectively,

extending from the top to the bottom ofthe casing 1,

this shaft being positioned centrally of the 4. The front or inner center compartment side of compartment A is closed by a suitable screen 18 and the outer ends of compartments 3 are closed by screens 19.

The casfan will be rotated ing vis further provided with closure memfigure, is opened, the other door 20 being closed, this permits air to flow downwardly through the left hand end compartment 3, this air escaping from this compartment through screen 19. The air strikes the vanes of wind wheel 6 thus rotating the same and, by means of the belt 11 rotating fan 13. The fan 13 when thus rotated will cause a current of air to flow into. the car so as to ventilate the same. When travelling in the opposite direction door 20 at the left hand end of the housing as considered in Figure 2 is closed, the door at the right hand end of the housing being opened. In this case the in theother direction and will act as a suction fan so as to remove heated air, smoke, etc., from the interior of the dining car, the car through the ventilators at the top thereof usually provided for this purpose. In either case the fan 18 is rotated and acts to cause a current of air to flow through the car thus obtaining a very decided cooling effect and very efficient ventilation of the car. In practice I will mount a ventilator in each window of the car and the combined effect of these ventilators is sufficient to very materially cool the entire interior of the car, obtaining thorough ventilation thereof and removing any vapors, heated air and other products caused by cooking on. the ranges of the dining car. As will be noted more clearly from Figures i and 5, I provide opening 22 through the back or top wall of each end compartment 3, these openings permitting the escape of cinders or other foreign materials. Such materials can readily escape from the center compartment t as the outer side of this compartment is open except for the causing fresh air to enter.
